1. An annular dome switch comprising:
- an upper dome sheet; and
an underlying substrate;
wherein the upper dome sheet extends from the underlying substrate defining a raised cross-sectional shape, the raised cross-sectional shape extending at least substantially along a length of an annular shaped path, wherein;
the underlying substrate comprises two substantially continuous annular concentric connection pads, connection pads, the two substantially continuous annular concentric connection pads comprising an inner annular pad and an outer annular pad, each having opposite ends, one end of said inner annular pad being connected to one end of said outer annular pad by a radial element and opposing ends being connected to a detection circuitry; and
the upper dome sheet is configured to make electrical contact with the connection pads of the underlying substrate when the upper dome sheet is depressed towards the underlying substrate such that the electrical contact completes an electrical circuit and that a length of the substantially continuous annular concentric connection pads in the electrical circuit is dependent on where the electrical contact is made.

Abstract
An input apparatus for a multimedia device, said input apparatus comprising: a rotator wheel having an upper planar surface that is substantially annular in shape and exposed in order that the upper planar surface may be accessed by a user of the multimedia device; means for detecting rotational movement of the rotator wheel about an axis perpendicular to the upper planar surface of the rotator wheel; and select means activated when a pressure is applied to the upper surface of the rotator wheel in a direction substantially parallel to an axis perpendicular to the upper planar surface of the rotator wheel.
